Tuna, Bigeye – Unassociated Purse-seine (Maguro)

Bigeye Tuna can grow to over 440 lbs. and live for 10 years. Female Bigeye Tuna are very fertile (otherwise known as “highly fecund”), releasing millions of eggs each year. Bigeye Tuna are found throughout the world’s tropical and sub-tropical oceans, with populations in the Indian, Atlantic and Pacific Oceans.

Bigeye Tuna have a medium abundance overall; however, some populations are healthier than others. Purse seine fisheries catch the majority of Bigeye Tuna worldwide, with most processed by canneries into canned tuna (labeled as Chunk Light tuna, along with Skipjack and Yellowfin Tuna). Bycatch levels are moderate, typically including other tuna species and sharks.
